Dono if I can run a 225 45 17 tyre without issues or would I be safer with a 215 45 17 tyre.

Not sure on sizes but do not go anywhere on a damp road with those tyres !! Took a drive to Cornwall once and it was raining , the most terrifying journey of my life , no grip and tram lining like you wouldn’t believe. Unless it’s a track car or only driven when it’s middle of summer or dry roads I would t go near them ….. bloody things lol

Just see how much clearance you have on your shock , it’s only 5 mm max each side so should be ok , vredestien ultrac are a very good grippy brand and not too much , other possible sizes would be a 40 profile , your speedo will be more accurate with a 225/45/17 as the tyres bigger and all speedos under read any way 👍 Toyo are they not track tyres as mentioned above ?

My GF8 is happy on 215/45-17. To be honest I looked at what Prodrive did with the RB5 and P1, and reckoned they probably knew what they were doing.😄

I can't measure anything as the car is all in bits as it's undergoing a full ground up build everything new.
The car will only be used in the summer, no wet use and odd track days.

What is your clearance like on the 215 tyres. Also is that on a 7 inch rim or 7.5

Compare the current clearances with the new combo using Scoobynets very own tyre/rim clearance calculator......
